What a great film, brings me right back to my early colour TV student days.
The early colour TV sets used a combi of transistor and thermonic valve(s)
During my training i remember having to do convergence and colour purity
adjustments, & believe me it was a nightmare. By to-day's standards the amount of components in them early colour set's was unbelievable and they were power hungry! Tkns for posting.
The Colour Receiver Installation film is an interesting part of TV history. The set-up of a colour TV tube was extremely complex. If anyone has ever tried to 'convergence' one they'll know what I mean. As colour tubes slowly disappear from the home and are replaced with LCD/Plasma etc, so too is the complex adjustments of the shadow mask colour CRT. The colour TV, at the time (c1967), must have been one of the most complex pieces of equipment in domestic use.
@aptsarchive Agreed, and this film explains how to get the best colour picture possible by tuning the picture the way an artist would tune their instrument. And IMHO it still holds true today.
@borgduck; on top of what aptsarchive said, you also have to realise that early colour sets were a lot less reliable and required many more adjustments to be made than more recent ones.
AFAIK many of these adjustments were later rendered unnecessary by engineering and reliability improvements or being automatically adjusted/corrected via microchip circuitry, etc.
Given the alignment necessary for colour TV, it often surprises me that they got it working *at all* back then.
@AidanLunn; I'm quite happy to believe the Sony was more reliable than its contemporaries, but I'm guessing it would still need more setting up and occasional tweaking than one (e.g.) built 25 years later.
I have a TV (Sony too) from the early 90s that has never been adjusted or fixed and still shows no sign of softening, aberration, etc. (Possibly that was the high water mark- I suspect quality may have declined from the late-90s onwards as things got *really* cheap, as with most stuff(?))
A new colour TV was nearly as expensive as a mini, thats why so many were rented by customers in the UK in the late sixties. But even so take up was very slow. It was a novelty feature of snob value for the well off for at least 3 years after launch.

Reminds me of the old TV engineers' joke:
"Good morning madam - I've come to check your purity!"

The United States had color TV as early as the mid 1950s.

Is that Michael Aspel's vocals...? Sounds like him but not sure....this is classic! Was this done by the COI...?

Yes, it is Michael Aspel doing the voice over. Think the film was made by the British Radio & Electronic Manufacturers Association.

Why silly! Colour sets were new, people were unsure of them, and needed to be explained - in great detail.

@aptsarchive I'm sure that when we bought our first colour tv in 1970 it cost over £200. That was a massive amount of money then.

@NotATube British ones weren't as reliable.
You can't say the same about the Sony KV-1320, though!!!

I know it's a cartoon, but is the TV supposed to be a Pye or a Philips G6?
TashkentFox 2 years ago
Have now idea what the tv set is supposed to be. It is assumed to be a generic colour television receiver of the period!
aptsarchive 2 years ago
At first the only colour sets on the market were made by Pye, Decca and Philips.

Gosh, when we got colour in 1972 I don't remember us needing such a large ariel - lol

@vidpop If you still only watch black & white tv, at least you don't have to pay as much for your tv licence!
